smatch correctly called out a logic error with accessing a pointer after
checking it for null:
drivers/scsi/lpfc/lpfc_els.c:2043 lpfc_cmpl_els_plogi()
error: we previously assumed 'ndlp' could be null (see line 1942)
Adjust the exit point to avoid the trace printf ndlp reference. A trace
entry was already generated when the ndlp was checked for null.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
